| Abstract: | The elastic finite-deformation problems be bring into the theoretical system of Lagrangian mechanics, the basic equations of finite-deformation for plane-strain problems andplane-stress problems be builded by the Routh method in classical mechanics,the contradictionin von Kdrmdn equation of finite-deformation large-deflection problems be disussed, and thenew plan be proposed in this paper. |
